In order to determ ine the structure param eters o f the reaction interm ediate form ed during the reduction process of chrom ate(V I) ion by hydrogen peroxide, a laboratory stopped-flow X-ray absorption fine structure (X A F S ) apparatus, which was constructed by a rotating an­ ode X-ray generator, an energy scanning spectrom eter, a stopped-flow assem bly, and X-ray detectors, was newly deve...

Transmission X-ray microscopy (TXM) has been well recognized as a powerful tool for non-destructive investigation of the three-dimensional inner structure of a sample with spatial resolution down to a few tens of nanometers, especially when combined with synchrotron radiation sources. Recent developments of this technique have presented a need for new tools for both system control and data anal...

A new version of the Monte Carlo event generator Dpmjet is presented. It is a code system based on the Dual Parton Model and unifies all features of the Dtunuc-2, Dpmjet-II and Phojet1.12 event generators. Dpmjet-III allows the simulation of hadron-hadron, hadron-nucleus, nucleus-nucleus, photon-hadron, photonphoton and photon-nucleus interactions from a few GeV up to the highest cosmic ray ene...

A postprocess analysis of a single time frame hydrodynamic profile from the PRISM two-dimensional MHD simulation of an argon gas puff Z-pinch plasma experiment on Double-Eagle generator at Physics Internationals, Co. is presented. In addition, spatially resolved emission spectra and filtered (Kand L-shell radiation) x-ray pinhole images, generated using the SPEC2D code, are examined toward the ...

The 3DCGiRAM is a 3D-graphic accelerator designed for photo-realistic image synthesis. The 3DCGiRAM is equipped with graphics processing units that perform ray-object intersection calculations and intensity calculations for rays traced over a 3D virtual object space. It also has a hardwareaccelerated 3D line generator, which effectively finds objects in a grid space that are likely to intersect...

An electron probe microanalyzer (EPMA) with a palm-size chamber including the electron source and the sample stage was developed using a pyroelectric crystal. Energy of obtained continuous X-rays and lower limits of detection of transition metals (titanium, iron, and nickel) were evaluated. End point energy (Duane-Hunt limit) of obtained continuous X-rays was about 40 keV, but the palm-size EPM...

Crystallographic end-stations require a significant investment in state-of-the-art equipment, as well as a significant effort in software development. The equipment often sits idle during annual maintenance shutdowns. In order to utilize the existing hardware and software during these shutdowns, we installed a sealed-tube microsource X-ray generator in the beamline 9-2 hutch at Stanford Synchro...
